WILLIAM I-I. FORD, OF LOWELL, MASSACHUSETTS, ASSIGNOR TO RINGSETCOMPANY, OF BOSTON, MASSACHUSETTS.

VISE.

SPECIFICATION forming part of Letters Patent No. 679,257', dated July23, 1901. Application filed October 19, 1900. Serial No. 33,648. (Nomodel.)

To o/,ZZ whom t may concern:

Be it known that I, WILLIAM H. FORD, a citizen of the United States,anda resident of Lowell, in the county of Essex and State ofMassachusetts, have invented an Improvement in Vises, of which thefollowing description, in connection with the accompanying drawings, isa specification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel vise forholding articles to be filed or finished, the vise being adapted tohold, among other things, finger-rings and the like.

My novel vise contains a yielding or springsustained support and ahorn-like jaw to enter the space in the hollow article to be filed, thesupport acting, preferably, against the outer side of the article.

Figure l in elevation shows my novel vise holding a linger-ring; andFig. 2 shows the vise in lon gitudinalxsection, the vise being inposition to receive a ring.

The vise shown embodying my invention in one good form may comprise ahollow handpiece A, which may be slotted at one end, as at a. 'Thehandpiece is shown as receiving within it a shank b, made hollow todecrease its weight, and provided with a screw-thread c, which isengaged by a nut d, which enters the enlarged end a of the handpiece,the nut having swiveled or lunited fixedly to it an engaging portion b,so that by rotating the engaging device the nut may be turned on theshank b to move it longitudinally in the handpiece. The nut is free tobe rotated in the handpiece, and to prevent it from longitudinalmovement therein the nut has been provided with an annular groove cl2,which is entered bya suitable pin or pins a2, fixed in the handpiece.The shank has secured to its Unthreaded end a jawf,l having a horn-likeend fl' to enter the hollow article, as a ring, to be filed or polished.The lower part f2 of the jaw is secured to the shank b in suitablemanner, as by a pin f3, the jaw entering and being movable in the slotct as the nut d is turned. The upper end of the handpiece receiveswithin it the stern g of a support g', the said stein being representedas hollow and as receiving one end of asuitable spring h, which acts tosustain the support yieldingly that it may be depressed or moved awayfrom the horn f' when a ring is put into the vise, the spring causingthe vise to hold the ring while it is being put into the desiredposition to be clamped firmly. The spring h is shown as connected at oneend with the jaw f. To prevent marring the exterior of the ring, Iprovide the sup- 6o port g with a piece of leather m.

With the vise in the condition, Fig. 2, the support g may be depressedto open aspace between it and the horn f for the entrance of the ring,and the ring having been inserted the spring will cause the ring to begrasped and retained loosely in position while the ring is adjusted intothe desired position. This done, the nut el may be rotated on the shank,causing the jaw to enter far- 7c ther the slot a, such movement of thejaw serving finally to seat the under side of the support g on the endof the handpiece, and any further rotation of the nut then clamps andholds the ring firmly for filing. 7

Having described my invention, what I claim, and desire to secu re byLetters Patent, 1s-- l. A vise, composed of a support, a hornlike jaw,means to move the same relatively 8o one to the other and clamp a hollowarticle inside and outside, and elastic means for forcing the supporttoward the horn-like jaw to loosely hold an article between them whilebeing adjusted in position.

2. In a vise, a handpiece, a support, a threaded shank, a jaw having ahorn-shaped end to engage the inner side of a hollow article, a nut tomove the jaw longitudinally with relation to the handpiece to clamp ag'o hollow article between them, and elastic means for forcing thesupport toward the horn-like jaw to loosely hold an article between themwhile being adjusted in position.

3. In a vise, a hollow handpiece slotted at 95 one end, a hollowthreaded shank within said handpiece, a horn-like jaw connected withsaid shank, a nut on said shank to slide it in said handpiece, and anindependent movable and elastic support having a projection roo andadapted to be seated on said handpiece.

u. In a vise, a handpiece, a spring-pressed support carried thereby andnormally projeeted beyond the end of the handpieoe, a

horn-like jaw, and`means to move said support and jaw relative to eachother to clamp l 5. A vise composed of a bodily-movable spring pressedsupport, a horn like jaw 1o against which the said support is normallypressed, and. means to move the said; support and jaw relatively one tothe oth er to clamp a hollow article inside and outside.

-In testimony whereof I have signed my name to this specification in thepresence of I5 two subscribing witnesses.
